Airworthiness Directives; The Boeing Company Airplanes
We are superseding Airworthiness Directive (AD) 2015-16-01 for certain The Boeing Company Model airplanes. AD 2015-16-01 required incorporating design changes to improve the reliability of the cabin altitude warning system by installing a redundant cabin altitude pressure switch, replacing the aural warning module (AWM) with a new or reworked AWM, and changing certain wire bundles or connecting certain previously capped and stowed wires as necessary. For certain airplanes, AD 2015-16-01 also required prior or concurrent incorporation of related design changes by modifying the instrument panels, installing light assemblies, modifying the wire bundles, and installing a new circuit breaker, as necessary. This AD retains all actions required by AD 2015-16-01. This AD was prompted by the discovery of a typographical error in AD 2015-16-01 that referred to a nonexistent paragraph. We are issuing this AD to prevent the loss of cabin altitude warning, which could delay flightcrew recognition of a lack of cabin pressurization, and could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.
Airworthiness Directives; The Boeing Company Airplanes
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD requires repetitive eddy current inspections for any cracking in the inspar upper skin, and related investigative and corrective actions if necessary. This AD was prompted by a report that an operator discovered a crack in a certain section of the inspar upper skin, just forward of the rear spar on the right wing. We are issuing this AD to detect and correct any cracking in the inspar upper skin and rear spar upper chord, which could result in the inability of the structure to carry limit load, or result in a fuel leak, which could prevent continued safe flight and landing.
Airworthiness Directives; Rolls-Royce plc Turbofan Engines

This AD requires reducing the cyclic life limits for certain high-pressure turbine (HPT) disks, removing those disks that have exceeded the new life limit, and replacing them with serviceable parts. This AD was prompted by RR updating the life limits for certain HPT disks. We are issuing this AD to prevent failure of the HPT disk, which could result in uncontained disk release, damage to the engine, and damage to the airplane.
Extension of the Prohibition Against Certain Flights in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) Flight Information Regions (FIRs)
This action extends the prohibition against certain flight operations in the Simferopol (UKFV) and Dnipropetrovsk (UKDV) flight information regions (FIRs) by all United States (U.S.) air carriers; U.S. commercial operators; persons exercising the privileges of a U.S. airman certificate, except when such persons are operating a U.S.- registered aircraft for a foreign air carrier; and operators of U.S.- registered civil aircraft, except when such operators are foreign air carriers. This action also revises the FAA approval process for proposed operations authorized by other U.S. Government departments, agencies, and instrumentalities to clarify the FAA's expectations regarding requests for approval and revises the approval conditions and information about requests for exemptions to reflect the termination of statutory authorization for the FAA's premium war risk insurance program. This action also makes minor non-substantive corrections to the wording of the rule. The FAA finds this action to be necessary to address a continuing hazard to persons and aircraft engaged in such flight operations.
Airworthiness Directives; Bombardier, Inc. Airplanes
We are revising an earlier proposed airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM proposed to require revising the maintenance or inspection program to incorporate revised tasks specified in certain temporary revisions (TRs) to the airplane airworthiness limitations (AWLs). The NPRM was prompted by the need for more stringent inspection requirements for certain affected components. This action revises the NPRM by proposing to require revising the maintenance or inspection program to incorporate certain revised AWL tasks instead of TRs, and by proposing to require repairs of affected components. We are proposing this supplemental NPRM (SNPRM) to detect and correct fatigue cracking in the affected components, which could result in loss of structural integrity. Since these actions impose an additional burden over those proposed in the NPRM, we are reopening the comment period to allow the public the chance to comment on these proposed changes.

This AD was prompted by the discovery, during routine overhaul of the LPT, of cracks in the barrel section of the LPT 4th stage IAS. This AD requires removal of the LPT 4th stage IAS, P/N 51N038, according to a prescribed schedule. We are issuing this AD to prevent failure of the LPT 4th stage IAS, which could lead to an uncontained IAS release, damage to the engine, and damage to the airplane.
Airworthiness Directives; Bell Helicopter Textron Canada Limited Helicopters
We are superseding emergency airworthiness directive (AD) No. 2015-16-51 (Emergency AD 2015-16-51) for Bell Helicopter Textron Canada Limited (Bell) Model 429 helicopters. Emergency AD 2015-16-51 required inspections of each inboard and outboard tail rotor pitch link assembly for axial or radial bearing play, and if there was axial or radial bearing play, removing the tail rotor pitch link and inspecting for wear. Emergency AD 2015-16-51 was prompted by several reports of worn tail rotor pitch link spherical bearings. We are issuing this supersedure to retain the inspection requirements in Emergency AD 2015- 16-51 while revising the applicability and compliance time to clarify that all Bell Model 429 helicopters require recurring inspections regardless of hours time-in-service (TIS) accumulated on the helicopter. These actions are intended to prevent pitch link failure and subsequent loss of control of the helicopter.
